SEAMING-MAOHINE.

Patented Nov. 17, 1908.

Application filed December 4, 1906. Serial No. 346,304.

To all whom 'it may concern:

Be it known that I, Sons QPSAL, a subject of the King of Norway, residingat btavanger, Norway, have invented certain 5 new and useful Improvements in Seaming- Machines; and I do hereby declare'thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper- 10 tains to make and use the same, reference be- I ing had to'the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in seaming machines and particularly to that class of machines, in which the seaming tools are controlled by two cams, the configuration of which is adapted'to that of the can to be seamed.

The objects of the invention are to provide means whereby one of said cams holds the seaming tools in contact with the seam, while the other cam serves as a kind of complementary cam to give the tools a steady movement; to provide an improved construction of the controlling rollers, whereby the seamin rollers, as .soon as the seaming is finishe are automatically released from their contact with the can whereby the operative period of the machine is, to a certain extent, made independent of the number of rotations.

A further object of the invention is to provide an improved construction of holder for the seaming rollers for the purpose of mak ing them easily adjustable.

, In the accompanying drawings, Figure 1 is a side elevation; Fig. 2 a. front elevation; 4 Fig. 3 a ground plan of a-complete machine,

embodying my invention; Fig. 4 is a vertical section on a larger scale through the upper portion of the machine; Fig. 5 is an .elevation of the same part of the machine 45 seen from the left of Fig. 4; Fig. 6 is a plan View of the controlling mechanism. Figs. 7

and 8 are respectively, a plan, and side view of the controller disks. Figs. 9, 10 and 11 are respectively, a side, end and plan view of one of the seaming rolls and the means for adjustably supporting them, and Fi 12 is an enlarged detail view of the means or connepiting the controller disks to the operating ro Corresponding andlike parts are referred to in the following description and indicated in the several views of the drawings by the same reference characters.

The frame of the machine comprises a standard 1 mounted on a suitable base A and provided near its lower end with a horizontal arm 2 in the outer end of which is formed a guide for a supporting rod 3. Said rod has on its upper end a head 4 for the reception of the cans to be operated upon and is provided with longitudinal ribs working in grooves in said bearing to prevent rotation. The head is held inthe operative position, shown in the drawings, by the follow ing mechanism. A sleeve 6 surrounds the rod, below the bearing 2 and is pivotally connected to two parallel rods 8 which rods are articulated to a rod 9 forming a knee joint 7 The lower end of rod 9 is fulcrumed in a bracket 10 and has a foot lever 13 connected thereto below the fulcrum and levers 8 and 9 are held in ,a vertical position by a spring 14 connected to the lever 9 and standard A. The rod 3 and sleeve 6 are detachably connected by means of a latch 11 on the end of the rod 3 taking over a flange 12 formed on the sleeve.

From the upper end of standard 1, an arm l projects parallel to the arm 2. In the arm 1 is fixed a depending tubular shaft 15 the axis of which is in a line with the axis of rod 3. A pulley 16 is rotatably mounted on shaft 15 and rests on a breast bearing 45, Fig. 4, and held against longitudinal movement on the shaft by a nut 47 and lock nut 48. This pulley carries two diametrically oppositely ositioned sleeves 17 and 17 in which are ournaled spindles 18, 19 respectively and on the ends of these spindles are keyed curved arms 20, 21 and 22, 23 respectively. The arms 20 and 21 on opposite ends of shaft 18 and the arms 22 and 23 on opposite ends of shaft 19 point in opposite directions to each other as shown in Fig. 6 and carry controlling rollers 24, 25 and 26, 27 respectively. On each of the arms 21 and 23 is also journaled a seaming roller 28, 29 respectively. Each controlling roller has a bevel. face 30 situated in a different horizontal plane and corresponding with similar faces 31 of two non-rotating controller disks 32, 33. One form of controlling disk is shown in plan in Fig. 7 but these disks may be of any configuration to conform to the shape of the can to be seamed. Each-controlling roller 25 and 27 has an additional bevel face ,34 inclined in the opposite direction to that of the bevel faces 30.

The controller disks surround the shaft and are movable longitudinally thereof into and out of contact with the bevel faces of the controlling rollers by means of a rod- 35, slidably mounted in the tubular shaft 15. The means here shown for connecting the disks with the rod 35 consists of lugs 36, 37 which project from said rod through slots 38 in the shaft 15 and rings 39, 40 which surround said shaft and slide thereon are secured to the lugs by screws, said rings bein provided with peripheral threads onto whic the disks are screwed. Guide rods 41 are secured to disk 32 and extending above and below the same slide through plates 42 and 43 fixed on the shaft 15 on each side of said disk. Disk 33 slides on stationary guide rods 44 which have their upper ends thread ed in the fixed breast-bearing 45 of the pulley; the lower ends of said rods supporting a forming headg46 on the end of shaft 15.

The rod 35 projects through the top of shaft 15 and is hinged to one end of a lever 49, fulcrumed on a bearing 50 on the arm 1 of the standard 1. A hand lever 51 is fixed to the lever 49 at the fulcrum oint and on the free end of the latter lever is mounted a socketed member 52 designed to take over the upper end of a stem 54, slidably mounted in a bracket 53 on the standard 1 and normally held in a raised position by a spring 55. The stem extends through a slot (not shown) in the standard 1 and its lower end normally rests against the operating end of the latch 11 so thatwhen the stem is depressed, as hereinafter described, the hook of the latch will release the sleeve 6 and allow the rod 3 to drop.

An operating shaft is shown journaled in the base A and standard a and carries a driving pulley 63 and a fixed and loose pulley 64, 65 respectively. A driving belt (not shown) is passed from either of the latter pulleys over guide rollers 66 to pulley 16 and may be shifted by a rod 57, carrying a belt guide 56, said rod being slidably mounted in consoles 58. This rod 57 is connected by a pin 59 to one end of a lever 61 which is pivoted at 60 to the base and has at its opposite end a foot plate 62. The bearings for the rod 57 in said consoles are sufficiently large to permit the slight lateral movement of said rod which is imparted thereto by the are described by the movement of lever 61.

To the arms 21 and 23 are secured holders 71 in which forks 72 that carry rollers 28 and 29 are mounted. These holders have parallel jaws 71", 71*, between which is mounted a sleeve 73 provided with a threaded shank 74 which passes through'the holder. I The shanks of the forks exten jaws and sleeve, and by moving said shanks through thelongitudinally or axially rotating them a proper adjustment of the seaming roller may be attained. When properly ad usted a nut 75 on the end of the threaded shank will draw the sleeve 73 out of alinement with the jaws 71, thus clamping the fork-shank in its adjusted position.

The machine operates in the following mannely The can to be seamed is placed on head 4, footlever 13 is pressed down; and

'bars 8, 9 will thereby form a knee at 7, and

the clutch-block 6 pulled down, until latch 11 will catch with lug 12 on the clutch-block 6. spring 14 will then force bars 8, 9 and rod 3 wit-h its head 4 back to the-position shown in Fig. 1, in which position the can is retained between the head 46 and head 4. By forcing down the foot plate 62 the belt passes from the loose pulley 65 across to the fixed pulley 64, whereby pulley 16 is rendered operative together with the seaming instruments. The seaming operation is now eflected by pulling the lever 51 to the right from the position shown in Fig. 1 whereby an upward movement is imparted to controlling disks 32, 33, coincident with the downward movement of Footlever 13 is now released, and the' the member 52 on the lever 49. The bevel edge 31 of disk 32 will then first bear upon the bevel face 30 of controlling roller 26 forcing it outward, whereby seaming roller 29 on arm 23 comes into contact with the can by means of arm 22, shaft 19 and arm 23. While this goes on the bevel face 30 of controlling roller 27 is riding upon the bevel edge 31 of controlling disk 33, thereby steadyingthe seaming instrument's. When the bevel edge 31 of plate 32 has passed the bevel face of roller 26, it bears upon the bevel portion of controlling roller 24, pressing it outward, and seaming roller 28 is brought into contact with the can in the same way as already indicated for seaming roller 29. As soon as the edge of disk 32 has passed the highest edge of the bevel face 30 of roller 24, the edge of disk 33 first bears upon the little bevel face 34 of roller 27,

thereby releasing seaming roller 29 from its contact with the can, and then it bears upon the bevel face 34 of controlling roller 25, releasing seaming roller 28 from contact with the can; immediately afterwards the socket 52 on lever 49 strikes a ainst the upper end of stem 54 pressing it ownward, Y

thereby releasing latch 11 from lug 12 on clutch part 6 and permittin bar 3, head 4 and the can to come down. oincident herewith footplate 62 is raised by the toe of the ing the sleeve 6 until it is engaged by the latch 11. As soon as the operator removes his foot from lever 13 levers 8 and 9 are returned to their vertical position bythe acthe can is raised into seaming position. Lever 6-2 is again depressed to shift the belt from the loose to the fast pulley, and as soon as the operator begins to pull the lever 51 toward the right, from the position shown in Fig. 1, the seaming operation is resumed.
